The Lewis dot structure are the diagrams that represent the valence electrons of atoms in a molecule. It is used to show how the electrons are arranged around individual atoms inside a molecule. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared pair or non-bonding pair. Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure. Electron pairs are therefore considered lone pairs if two electrons are paired but are not used in c…
